'UNDER-SEA-ILLUMINATING MEANS FOR SUBMARINES.

Application 1ed April 8,

This invention relates to certain new and useful improvements in undersea illuminating means for submarines and has for one of its objects toprovide a searchlight carried by a side wall of the submarine with ahinged cover for the light opening at the outer side of the wall andwith an electrically charged device movable toward the light openingwhen the cover therefor is raised to prevent sea monsters and the likefrom charging the light opening.

A further object of the invention is to provide in a submarine structureof the type above set forth, an observation window in proximity of thesearchlight with a manually shiftable cover wall therefor.

It is a further object of the invention to provide devices to cause theelectrically charged device to move in proximity of the searchlightopening upon elevation of the cover for the light opening in` a singleoperation.

Vith the above general objects in view and others that will appear asthe nature ofthe invention is better understood, the same consists ofthe novel form, combination and arrangement of parts hereinafter morefully described, shown in the accompanying drawings and claimed.

In the drawings, wherein like reference characters designatecorresponding parts throughout the several views, v

searchlight comprising a casing 3 containing a lamp having electric cordconnection 6 with the socket 7 as shown in Fig. 2, the casing beingsupported upon the inner face of the side wall 2 of the submarine with awatertight lens 8 set in the opening in the outer end of the casing. Aclosure doorI 9 horizontally hinged as at 10 to the outer side of thewall 2 covers the light opening when the light is out of use and isadapted to be elevated tothe position shown in F ig. 2.

For the purpose of preventing sea monsters and the like from gatheringaround the searchlightwhen the same is in use, the electrically chargeddevice illustrated in Figs. 5 and 6 is adaptedto be shifted to aposition adjacent the searchlight opening in the submarine wallsimultaneously with the opening movement of the closure door 9 and suchdevice comprises a pair of metallic plates 11 and 12 spaced by the plateof insulation 13 and secured together in any manner, the rear side ofthe metallic plate 11 carryingv tubular bearings 14 that are slid-l ableupon the guide rods 15 carried by the outer face of the submarine lwall2 and spaced therefrom by the insulating collars 16. Prongs 17 anchoredto the metallic plate 11 as at 18 pass through openings -19 in theplat-e 12and are insulated from the plate 12 by the insulating blocks20. Similar prongs 21 are anchored as at 22 to the metallic plate 12 andare spaced from the metallic plate 11 by the insulating strip 13, thisconstruction being clearly shown in Fig. 5.

Any number of searchlights may be carried by the side wall of thesubmarine and arranged in proximity of the searchlight are observationwindows, one of which windows is illustrated and designated by thereference numeral 23 with which an overlying hinged cover 24 isassociated, the cover being horizontally hinged for vertical swingingmovement at the upper edge of the window.V The operating means for thehinged window cover 24 is operable from within the subllO Y casing 3.

The devices for opening and closing the cover wall 9 Jfor thesearchlight casing and for raising and lowering the electrically chargeddevice upon the guide rods l5 eects simultaneous operation 'of thesemembers and such devices include, asfshown in Fig. 4 a pair olvertically spaced bracket bearings 28 and 29 `that rotatably supportcord winding drums 30 and 3l respectively. il s shown in Fig. 2, thecord 32 passing over the guide urum'il tl et journaled i-n the bracket34; upon the side wall l 'or the subn'iarine has one end thereof passingoer guide pulleys 35 and directed through an Aode-ningin -the side wall2 lior attachinefntV at 3G -to the outer side oi the free swinging endor the hinged cover 9. The outer end of the cord 32 passes over thedrums and 30 in the manner -indicated in Figs. 2 and l and passingthrough an openingin the side wall 2 ofthe submarinefbody is attached to`the inner side or the free swinging end or the cover 9` as at 3'?.
